Title: Control arrangement for controlling the air gap between rails and magnets of an electromagnetic levitation vehicle
Inventor: GOTTZEIN EVELINE
IPC: B60L13/06
Filed: 1984-05-11
Abstract: The invention relates to a control arrangement for controlling the air gap (s) between rails and magnets (1) of an electromagnetic levitation vehicle. The control arrangement has a controller (4) to which air gap (s) and magnetic current (I) or a magnetic flux ( psi ) are fed as system-inherent measuring variables in order to influence the control variable (U) for the magnets (1). In order to eliminate the sensitivity of the control circuit, associated with this kind of control, to fluctuations of the working point of the magnets, it is proposed with the invention that the critical control parameters (k) be adjusted automatically for the purpose of adaption to the changed operation conditions. For this purpose, a discrete viewer (2) is provided which forms estimate values (s, /s, I) from the measuring variables taking into account the measuring faults and feeds these estimate values to the controller (4). In order to support the formation of estimate values, a fault viewer (3) can serve to estimate the disturbance force (f), this fault viewer (3) being isolated from the discrete viewer (2) in terms of control technology.   <IMAGE>

Title: Valve-actuating device
Inventor: ANGERMAIR ERNST
IPC: E05F15/50
Filed: 1984-05-23
Abstract: Valve-actuating device, in particular in a pneumatic reversing valve, for admitting pressure to working cylinders belonging to door-closing systems and having closing and opening chambers. The valve is mechanically connected to an electric motor in such a way that its output variable, converted via intermediate gearing means into a linear adjusting movement, displaces the valve slide in each case into a different end-stop position as a function of the polarity of the supply voltage activating the electric motor. This results in a bistable character inherent in the entire switching arrangement of electric motor and reversing valve so that complicated mechanical means (switching levers and the like) ensuring a bistable switching behaviour of a door valve can be dispensed with. <IMAGE>

Title: Trailer control valve
Inventor: SCHULZ HANS-JOACHIM
IPC: B60T15/24
Filed: 1984-07-26
Abstract: The invention relates to a trailer control valve for a dual line brake system. The trailer control valve has a first relay piston (48) and a second relay piston (7, 8, 23), comprising two relay piston parts connected in series and fixed to one another. In the second relay piston a combined inlet and outlet valve (45, 6, 4) is arranged, by way of which a pressure medium inlet chamber (38) can be connected to a pressure medium outlet chamber (5), connected to a pressure medium outlet (10), as a function of the position of the first relay piston (48).

Title: Apparatus for the individual separation of flexurally slack sheet-like structures
Inventor: AURICH HORST DIPL ING
IPC: B65H3/22
Filed: 1984-10-09
Abstract: The invention relates to an apparatus for the individual separation of flexurally slack sheet-like structures, especially for the garment-making industry. The solution according to the invention has the object of overcoming over the surface the adhesive forces acting between the uppermost layer and the subsequent layer of a blank stack and of thereafter lifting off the layer. The apparatus consists of rotatably and slideably arranged separating heads or segmental rollers, on which needle rows are arranged preferably by means of needle carriers. The needle rows make a positive connection with the surface structure of the uppermost layer of the blank stack. During the separation, as a rule two blanks are first lifted, and in the further course of the separating operation the uppermost blank is detached from the subsequent blank by means of shearing stresses, starting from the active region in the direction of the stack edge, and subsequently is lifted over the surface. <IMAGE>

IPC: F16H61/04
Filed: 1984-11-02
Abstract: A gear-changing system for motor-vehicle reduction gears with interruption of the traction force, is designed in the manner of a semi-automatic unit. Using the manual controls (80, 81) which are connected to a control unit (82), gear-change forks (33) are operated via servo-systems (90). Sensors operate in conjunction with rotating marks on the drive shaft and with marks on the gear-wheels driven by the drive-shaft. By means of a phase detector (75) the phase position ( phi ) is determined between the gear wheels and the gear-change sleeves driven by the drive-shaft. When a predetermined phase position is attained, these elements are closed.

Title: Process for producing gas concrete bricks
Inventor: KLINGSCH WOLFRAM PROF DR ING
IPC: C04B28/02
Filed: 1984-12-07
Abstract: The novel process for producing gas concrete bricks is indicated, in which an autoclave treatment is not necessary and by means of which solid bricks and hollow-shaped bricks, in particular formwork bricks, can be produced. For this purpose, it is provided in the process for producing gas concrete bricks, finished elements or the like, the fresh concrete being mixed from binders, natural and artificial aggregates and water as starting materials, and a gas-forming propellant such as aluminium powder being mixed in, and the fresh concrete being cast into at least one mould and caused to harden, that conventional cement is used as binder and usual natural and broken sands are used as aggregates, the fresh concrete is filled into individual moulds for each brick and then dried in air. A very highly preferred further development of the process is characterised in that initially the starting materials are mixed in a high-speed mixer to give a chemically activated system, that a concrete plasticiser is added and that, finally, the gas former is mixed in and the resulting expandable mass is cast into the moulds. As a result, substantially higher strengths than hitherto can be achieved in gas concrete. The bricks can either be cast as such in moulds or be formed by sawing after the casting of large blocks.

Patent DE-3512051-A1 (DE)
Inventor: SCHINDLER MANFRED
IPC: B60G11/26
Filed: 1985-04-02
Abstract: The invention relates to a hydropneumatic suspension system for a tracked-vehicle chassis component, having a circular-arc suspension member fitted within a housing. This circular-arc suspension member is located between a support fixed on the housing and a rotating abutment. The housing is hinged on pivot points by means of a suspension arm fixed on the housing and the abutment by means of a hinging lever. Very little space is provided for the suspension of chassis components in such vehicles. Moreover, the suspension system must also be maintenance-free and easy to assemble. According to the invention, this is accomplished either by causing the suspension arm and the hinging lever to form, together with the pivot points fixed on the vehicle and a parallel control arm connecting the hinging lever with a pivot point, a parallelogram, or by hinging the suspension arm on a lower pivot point fixed on the vehicle, and by providing a pneumatic control arm connecting a higher pivot point fixed on the vehicle with the hinging lever, and by locating in the expanded position the hinge joint between the pneumatic control arm and the hinging lever on the side, turned toward the suspension arm, or an imaginary connecting line between the pivot point and the housing axle.

Title: TDMA point-to-multipoint communication system
Inventor: SPERLICH JOSEF DIPL ING
IPC: H04L5/16
Filed: 1985-08-10
Abstract: For a TDMA point-to-multipoint communication system with a central station (Z) and a plurality of sub-stations (U1, U2, ...), the frame structure is selected in such a way that the central station (Z) first transmits the bursts (B1, B2, ...) for the sub-stations which are the greatest distance away and the sub-stations transmit back to the central station (Z) in reverse order. Buffer memories (SPZ, EPZ, SPU, EPU) are provided in the central station (Z) and in the sub-stations (U) to convert continuous signals into burst signals and vice versa. The waiting times of the sub-stations are defined or the start times are determined for the respective burst transmission of the sub-stations via corresponding control units (STZ, STU). Furthermore, sync words and information relating to the waiting times of the sub-stations are inserted in the transmission frame by the control unit (STZ) of the central station (Z). This communication system is suitable for transmission via both cable and radio (Fig. 1). <IMAGE>
